PLACING CONTAINERS IN PROJECTILES.

Original application filed August 3, 1911, Serial No. 642,294. Divided and this application filed November 16, 1911. Serial No. 660,631.

To all whom it may concern Be it known that I, Emvs'r SoKoLowsKI, a subject of the Emperor of Germany, residing at Hamburg, Germany, have invented anew and useful Improvement in Placing Containers in :Projectiles, of which the following is a full, clear, and exact description.

I-lcretofore explosive charge containers for gunswere prepared in such manner that it was possible to place them with a small free space into any desired projectile of their type. This small space between the outer wall of the explosive charge containers and the-inner wall of the projectile was filled in diiterent ways. A known'metho l for the elimination of this free space con-- sists in pouring into the projectile suitable molten filling materials, for instance paraf-.

tin, and in pressing the explosive charge container'into the projectile and the paratlin The molten material in contained therein. this manner was forced to rise 1n the space between the explosive charge container ,and the inner wall of the projectile.- When this filling material which on one hand adheres to the explosive charge container and on' the other hand to the inner wall of the projectile is chilled, a fixed position of the explosive charge container in the projectile is insured. This method however, offers the following disadvantage: It frequently occurs that the molten paraiiin fills the empty I umn strongly presses in the explosive charge container against the latter in a backward and in a backward and sidewise. direction, and the explosive charge attempts to expand to the outside of the container on those places wbere-the latter does not find a strong resistance, for instance on those places where there are empty spaces betweenthe,

explosive charge container and the inner wall of the projectile. hen'ever this pressure is very strong during the first moment of the shot, it is liable to occur that the entire'rear end of the container is expanded, the plastic paraffin yielding to the front and escaping the pressure, being under the 111 this manner, whenever the force is sufiiciently strong, the conditions are favorable for a spontaneous ignition, for instance of the trinitrotoluol, by means of shock, friction and pressure. Even when in some instances aspontaneous ignition of the charge does not take place, it is possible that the center of gravity of the explosive charge is changed owing to the contraction of large explosive charges, thus affecting the uniformity of the line of flight. of the projectile.

Still less favorable are the conditions, when the filling material, for instance, molten para-flin, is poured from above into the empty space after the explosive charge container has been put in place; When using this method the filling out of the empty space is still more uncertain. The paraffin is chilled so quickly that a filling of the empty space at the most endangered part, the lower part of the explosive charge container, is not insured. It is not. advisable to purposely enlarge the empty space in order to insure a satisfactory pouring of the parattin without the formation of empty spaces,

due to the fact. as has been stated, that the yielding material in the case of an especially strong impact is capable of escaping from the back toward the front. a phenomenon which is bound to take place the sooner, the larger the empty. space between the explosive charge container and inner wall of the projectile. In this manner.

furthermore, the size of the explosive charge container, and as a consequence thereof the siae-of the explosive charge itself. are decreased in an undesirable manner, and a thick elastic material is presentbetween the explosive charge container and the inner j and .the remaining container and the wall ofthe projectile-arc the fused explosive, f or iii-'1 stance, trinitrotoluol.
